Optimizing Manpower Selection.

Abstract

Electroencephalograms were obtained with conventional scalp disk electrodes bilaterally at frontal, temporal, parietal and occipital locations. Two sets of computer analyses were performed. The first consisted of transforming the data from the time domain to the frequency domain Fourier Transformation. The spectral measurements were input to a Linear Stepwise Discriminant Analysis which acts as a feature selector. Analyses revealed that the most consistent difference between the disabled readers and the normals was the degree of shared electrical activity between symmetrical locations in the two hemispheres, the absence of a well-developed narrow-band peak in the alpha band in the dyslexics and a narrow band alpha peak like that in normals in those dyslexics who had benefitted from remedial programs.
